The
Main Controls
tab controls the PLL settings (see Figure 34).
Use the
Reference Frequency
text box to set the correct refer-
ence frequency and the reference frequency divider. The default
reference frequency in this box is 25 MHz (change this value to
10 MHz if using the supplied on-board TCXO).
Use the
RF Settings
section to control the output frequency.
You can type the desired output frequency in the
RF VCO
Output Frequency
text box (in megahertz).
In the
Registers
tab, you can manually input the desired value
to be written to the registers.
In the
Sweep and Hop
tab, you can make the device sweep a
range of frequencies or hop between two set frequencies.
In the
Latches/Registers
section at the bottom of the
Main
Controls
tab of the main window, the values to be written to
each register are displayed. If the background on the text box is
green, the value displayed is different from the value actually on
the device. Click
Write Rx
